	2	* Block D1 — Semantic code search UI + reindex trigger.
	3	*
	4	* GET /:owner/:repo/search/semantic?q=... — results page (ILIKE parity)
	5	* POST /:owner/:repo/search/semantic/reindex — owner-only, fire-and-forget
	6	*
	7	* Intentionally tolerates a missing DB / missing repo / missing index so the
	8	* page is always navigable. When there's no index yet, the page shows a
	9	* "Build index" CTA pointing at the reindex endpoint.
e3eb5ffClaude	10	*
	11	* 2026 polish:
	12	* - Scoped `.ss-*` CSS — sits below RepoHeader + IssueNav.
	13	* - Eyebrow + display headline + 1-line subtitle.
	14	* - Prominent search input w/ focus ring + gradient submit button.
	15	* - Result cards show file:line in mono, snippet, and match score chip.
	16	* - Dashed empty state w/ orb + Build/Reindex CTA when no index exists.
	17	*
	18	* All query strings + POST handlers preserved verbatim.
